The Ultimate Guide to Repairing a Damaged Skin Barrier

Skin barrier damage can take many different forms, ranging from sensitivity and redness to cracking and flaking. But what exactly is a skin barrier and how can we repair it when its broken? We’ve created the ultimate guide to answer the internet’s most Googled questions surrounding our skin barriers and what we can do to ensure a healthy, trouble-free complexion.

What is the skin barrier?

In simple terms, the skin barrier is the outer layer of the skin (also known as the epidermis). This barrier is actually made up of several layers that all serve their own function but usually when damage occurs, it’s to the outer layer.

The main function of the skin barrier it to prevent dehydration, keeping moisture within the skin, and shielding it against breakages - think of it as your complexion's own security guard. This special barrier is actually made up of three subdivisions: the chemical barrier, the stratum corneum and the moisture barrier.

To help you really understand how the skin barrier works, let’s run through each subdivision. First up, the chemical barrier. This is the outer section of the skin barrier and is formed from a variety of friendly skin microbiome that require a slightly acidic pH to function well. A disrupted pH balance can often break this section, which is why finding microbiome-friendly skin care routine is imperative.

Next, the stratum corneum. Made up of dead skin cells, this layer plays the role of protecting the skin and can often be damaged by over-exfoliating. The final section is the moisture barrier which yep, you guessed it, is responsible for preventing moisture loss. It’s made up of ceramides, free fatty acids and cholesterol, and requires the correct maintenance to prevent any breakages.

What causes skin barrier damage?

Skin barrier damage can occur due to many external factors, as well as some internal. Some of the main factors include:

  • Excessive exfoliating and overwashing
  • Pollution
  • A poor skin care routine
  • Dry air
  • Ageing
  • Lack of sleep
  • Genetics

How do you repair a damaged skin barrier?

  1. Reduce how often you wash your face

We’re not saying you should completely cut out your skin washing routine, but sometimes, stripping it back to basics can really give your skin the time to heal. We recommend cutting back on regular face washing, and, when it does come to cleansing, try using all-natural products that boast a mixture of moisturising properties. Low pH cleansers are also recommended

2. Cut back on the exfoliators

We know, nothing leaves our skin feeling fresher and softer than a chemical exfoliator. But, when the skin barrier is broken, it is so important to allow your complexion to heal. Unfortunately, in most cases, exfoliators only exacerbate the damage. Try stepping away from the scrubs for a couple of weeks (or until all signs of damage have cleared) before reintroducing a gentle scrub.

3. Moisturise

This stage is a given. If skin is visibly dry, cracked or broken then you need to find a deeply nourishing hydrator ASAP. We recommend looking for moisturisers that have water-retaining ingredients in, such as allantoin, hyaluronic acid, glycerin and panthenol.

To strengthen broken skin, try adding vitamin C-infused products into your routine. This special vitamin helps the skin’s cells to regenerate and is rich in antioxidant and anti-inflammatory ingredients.

4. Catch those zzz’s

Getting a good night’s sleep can work wonders for you skin as it allows your body to heal and regenerate properly. Treat yourself to a pamper evening before spritzing your bed with a relaxing pillow spray and settle in for the night.

5. Keep your skincare routine simple

When your skin barrier is broken, introducing a new product or an excessive number of steps into your skin care routine is an absolute no-go. Keep things simple with an all-natural skin care routine or products that are microbiome friendly and focus on moisturising.

Not sure what to look out for when buying barrier-repairing products? We recommend shopping for skin care essentials that are rich in fatty acids, ceramides, niacinamide, aloe vera, calendula and/or centella asiatica.
